The Trojan Gravity Flow Hog Nipple (Model 75) lets you turn a water barrel, tank, or even PVC pipe into a gravity-fed drinker—no pressurized system required. Designed to install through a 7/8" hole with a secure lock nut, it’s built to create a dependable, watertight connection so your watering setup works like it should (and not like a slow-motion leak test).
